Motion
A change in position over time
Net Force
The combination of all forces acting on an object
Speed
Distance traveled per rate of time Speed = distance/time
Velocity
The speed and direction of an object
Acceleration
The rate at which velocity changes over time
Newton’s First Law

Newton’s Second Law
Force = mass x acceleration
Newton’s Third Law
For every action there is an equal but opposite reaction
Inertia
The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object
Friction
A force that resists motion
Mass
